Enrich Notion Pages in n8n: Expand Related Properties

Enrich Notion pages in n8n by expanding relation properties (including nested ones)

This n8n workflow takes a Notion page object and a list of property names to expand, then resolves your Notion relation fields into the related page data—returning the original page object enriched with the requested nested properties.

What this workflow does

Built to be called from another n8n workflow, it performs the following steps:

• Receives inputs: a Notion page object and a Properties list (property names to expand).
• Splits and iterates: the requested properties are split into individual items and processed one-by-one.
• Resolves relations: for each property, it calls the “Get Relation Info” sub-workflow (ID: 14yGdu1YOQ0RgCzZ) to convert the Notion relation property into related page data.
• Expands nested properties recursively: if the property definition includes nested properties to expand and the resolved relation data is not empty, the workflow iterates through related items and recursively calls itself to expand nested relation fields.
• Aggregates results: resolved properties are collected across iterations.
• Merges into the original page: the aggregated resolved property objects are merged back into the original Notion page and output as an enriched page.

Use cases

• When your parent workflow fetches a Notion page, use this workflow to expand relation-based details for downstream processing.
• Build richer automations where a page’s related items must also have their own nested relation properties expanded.
• Support SaaS operations or reporting pipelines that need fully hydrated Notion data without manually joining relations.

Technical details

• Integration: Notion (via the “Get Relation Info” sub-workflow, plus any Notion calls it performs).
• n8n nodes/logic used: if, set, code, split out, aggregate, split in batches.
• Workflow design: called via Execute Workflow from a parent n8n automation, returning an enriched page object.
